th ion is bone stock never even took it apart it still has the battery that the factory gives you in the board i find there alot more hastle then the vibe plus there coming out with new boards for it so it will prolly keep up with ions soon enough?

if you sell your ion to buy a new vibe, assuming your ion isnt insanely upgraded, a new vibe will cost more than your ion will sell for or right about the same ($140-$150). and thats assuming your ion as a few good ups (reg, asa, feedneck, barrel, board maybe) unlesss you'll only be using co2, you might as well stick with your ion, although i do say the vibe is more durable and reliable.

i say ion
i had a similar problem debating over getting the vibe or the ion for only like $15 more. i was impressed with the vibe but i still prefer the ion. i think its better overall with rof and its more customizable. So really you cant go wrong with the ion.
